+<p>Synapse v1.81.0 deprecated application service authorization via query parameters as this is
+considered insecure - and from Synapse v1.71.0 forwards the application service token has also been sent via 
+<a href="https://spec.matrix.org/v1.6/application-service-api/#authorization">the <code>Authorization</code> header</a>], making the insecure
+query parameter authorization redundant. Since removing the ability to continue to use query parameters could break 
+backwards compatibility it has now been put behind a configuration option, <code>use_appservice_legacy_authorization</code>.<br />
+This option defaults to false, but can be activated by adding </p>
+<pre><code class="language-yaml">use_appservice_legacy_authorization: true 
+</code></pre>
+<p>to your configuration.</p>

 <p>Application services can no longer call <code>/register</code> with a <code>user</code> property to create new users.
